Building Elevation and Subgrade (BES)
The Building Elevation and Subgrade data contains New York City building centroids derived from the Department of Building's (DOB) February 26th, 2022 building footprint dataset. Each record contains a grade and first floor measurement for each building (recorded as feet above sea-level in the NADV88 vertical datum) and indicates if subgrade space exists. DCP contracted with an external data vendor to generate a single point, or centroid, that represented the location of the center of every building recorded in the DOB dataset. The dataset excluded the footprints of small accessory buildings such as sheds. Each row within the dataset represents one building centroid, and records the X and Y coordinates of that centroid in the NAD 1983 coordinate system.

Columns
Each source column, with the name and type we use to store it.
5 of 30 columns carry a concept; 30 carry a description from the publisher. Read the concept column before you join. A column with no concept carries no claim from us, and a name that looks like a key is not one.
